Use a Lan scanner or check in your router configuration the IP address. You can now put the SD card into the Pi and boot it.Īfter some time it should appear on your network. Safe the file with the name "wpa_nf" to the SD cards boot partition. (change country, ssid and psk accordingly) This will enable access to the pi through the terminal.Ĭreate a new file and add the wifi configuration of your network: country=SG # Your 2-digit country code - SG for Singapore in my casectrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevnetwork= " is unchecked.Ĭreate an empty ssh file and copy it into the SD cards boot partition. In that case its important that you check your textEdit preferences first: under "New Documents" "plain text" should be checked.:Īnd under "Open and Safe" "Add".txt. I used TextEdit on my Mac to create these files. One empty file named "ssh" and one file named "wpa_nf" You can of course also use other tools (etcher, Apple Pi Baker.) to install the system onto the SD.īefore the SD card goes into the Pi, we need to add manually 2 files into the boot partition: The easiest way is the official Raspberry Pi Imager: Starting from scratch, we first install Raspberry Pi OS onto the SD card. Navigate to “Advanced options”, hit enter.Installing Raspberry Pi OS and configure ssh and wifi access.Ssh Once logged in, launch the raspi-config GUI with the following command: Note: If these were altered before creating the backup, they will remain altered. Open a terminal window and login to your Raspi using the following SSH command.īy default the username is pi, the hostname is raspberrypi and password raspi.Boot the Raspi and ensure your computer is connected to the same wifi.In this case, launch a terminal on your Raspi and launch raspi-config as shown below. Note: If your restored backup runs a desktop version of Pi OS, you can skip the SSH-part and connect screen, mouse and keyboard before booting. We can do this in the raspi-config via SSH. Once the SD Card has finished restoring, the filesystem must be expanded. Thats it! Remember to expand the linux partition on the Raspi as shown below. As when backing up, this can take up to several minutes Click “Open” and wait for applePiBaker to finish up.Click “Restore” and locate the Raspi image backup.Make sure that you’ve disabled “Linux Partition Resize” in the options bracket! Note that this is opposite from creating a backup as shown above.Launch applePiBaker and select the newly wiped SD Card. Note that by default of SD Card Formatter, this will be named “boot”.You will need to authorize the process with admin credentials. Select the correct SD card and click “format”.Insert a disposable SD card that you wish to use for restoring your Raspi installation.When restoring a Raspi image to an SD card, the card must initially be wiped using SD Card Formatter prior to restoring your backup. Restoring a micro SD card from a Raspberry Pi backup Thats it! Eject your SD card and reinsert in your Raspi. This can take up to several minutes depending on the size of your Raspi installation. Click “Save” and wait for the imager to finish up.This step is it important and will save you both time and space from the resulting image file being compressed. Make sure that you’ve enabled “Linux Partition Resize” in the options bracket.Click “Disk to File”, and select a location for the image file.Click “Select Disk”, and click on your SD card:.Insert the SD card from the Raspi that needs backup.micro SD card from a functional Pi that needs backing upĭownload and install the applePiBaker softwareĭownload and install the SD Card Formatter software Backing up a micro SD card from a Raspberry Pi.Upon restoring, the image is burned to a new SD card in compressed state and subsequently expanded in the Raspberry Pi config. The resulting diskimage is a compressed file that mirrors the entire SD card. The backup is created with the imager tool applePiBaker. The most obvious reason relates to securing your prototype if something breaks, but it also allows you to quickly revisit old projects without setting up a new OS. When working with Raspberry Pi it can be useful to do complete backups of the SD card.
